My invention relates particularly to a coffee brewing apparatuswhich is designed to overcome many previous disadvantages, especially in coffee machines oflarge size.
The object of my invention 1s tor provide an apparatus in which cofiee'may bebrewed without the disadvantages inherent in previous constructions. The object is particularly to provide means whereby the cofiee may be I subjected to the'action ofthe water fed into the apparatus more effectively, in that the water being supplied'to the lower portion of the ground coffee prevents the coffee from compacting and, therefore, renders it more accessible to thebrewing action within the apparatus, and, furthermore, spreads the ground coffee outwardly andupflwardly duringthe rising current of water therein'solas to provide a larger area over a wider diameter in the body of coffee beingsubjected to the brewing action. This action, also, causes the coffee to be extracted gradually, part of thecoffee being floated upwardly to be last extracted by the water. The object is, furthermore, by this means, to avoid leaching out the deleterious mattersfrom the coffee as v 'ment in many different forms,"for the pur- 'much as possible by avoiding the necessity of making a strong extraction, such as would be the case were theground coffee to become compacted. Furthermore, by causing the spreading of the body of ground coffee outwardly and upwardly there is a pocket formed in the coii ee which causes'the water to seep out gradually through the sides of the body of coffee, and prevents the water passing out above the level of the coffee without passing through the same; Likewise, by feeding water upwardly in the body of coffee the tendency for the streamofwater to dig a hole in the body of theground coffee is avoided,-thus attaining better distribution of the water. in
-the cofiee, Furthermore,.by regulatingthe outlet of the water which is fed into the bottom of the body of coffee, as, for example, the arrangement andnumber of outlet holes, the distribution and quantity oflthe water can be regulated accordingly. This enables the most thorough extraction of the coffee to be attained for the given quantity of ground -coffee treated, thus producing a more uniform produced due to the fact that there is still v an effective extraction attainable in the brewing later in the periodot brewing than would otherwise be-the'case. Accordingly," the taste of the dregs in the coffee is avoided'at the end of the brew. 1 This result is aided by reason'of the fact that the top'layer of c'ofi'ee'remains until the last to be extracted. Furthermore, the water fed into the coffee stays hotter by reason of the central feed within the body of coffee. For the abovereasons itis not neces- 'sary to repour the liquid through the ground cofiee. This modeof operation enables coffee which hasbeen more finely ground to be used without compacting, etc. Again, in order to avoid stratificati'onof the different: strengths I e of coffee in the brew I have provided an equalizer pan which .causes the coffee to become mixed before bein'g'recei'ved in the bottom of the urn, whence it is drained off for use. In vadditlon, the construction is such! that the While my invention is capable of'ernbodi poseof illustration Ihave shown only certain forms of the same 'in'the accompanying drawings, in which- I I 1 V 1 is a sid' elev'ation of a cofiee appa- I :ratus made in accordance with'my'invention; Fig. 2 is a vertical section through the same;
v Fig. 3 isan enlarged side velevation of one r of the pivoted brackets for holding the coffeefilter cloth frame; p y 7 V v "Fig.4is a plan 'view showing'the arrangem'ent of thebrackets within the top of the I u e x Q Fig; 5 is a plan view ofthe distributer' nozzlefor the hot water, supply;
Fig.6 is a plan view of the equalizerpan; 7
Fig; 7 is a cross section ofa modification ofQ myinvention.
I he drawings, I have shown a cofiee apparatus comprising a hot water jacketl, having a filling opening 2 at the side thereof for the introduction of a body, of hot water 3, which is kept hot by the application of 'heat 10, the openings 9 and 10 being of such a size as to cause the accumulation of the strong brewed cofiee therein before passing out through said openings to the bottom of the urn 4- for mixing. with the brewed coffee therein. At the top of the apparatus there is a removable section 11 having therein a plurality of radially directed hinged brackets 12 supported from the. inner wall of the removable section 11, each of said brackets 12 having atits end an upwardly directed pin 13 for engagement with a coifee-filter-cloth 14 which is approximately hemispherical in Shape, and which is supported at its edges by means of a metalring 15. The pins 13 are engaged. with-the filter-cloth 14 just inside of the ring 15. A cover 16 is arranged to be removably applied to thQ'tOP of the removable section 11, but in such a manner as to per mit at one edge thereof, the entry of a hot water supply valve pipe 17 which enters at theside of the removable section 11 and has a. vertical end 18 provided at its lowermost portion with a circular nozzle 19 having laterally and upwardly directed holes 20 therein, the sizeand number of which may be varied according to the distribution of hot water desired in'the particular apparatus. Also, a screw-threaded clean-out cap 20 is provided thereon. The outer end of the pipe 17 has a downwardly directed portion 21 which is connected by a hinged shut-off valve 22, which closes when the pipe 17 is. raised to.
a vertical position, to a pipe 23 leading to a pressure hot-water supply tank 24 provided with heated water by a valve inlet pipe 25. In Fig. 7 I have shown a modified form of my invention, in which, instead of the pan 8 there is a cup 26 formed inte ml with the urn, having a lower aperture2 comparable to the aperture9, and instead of having the holes 10, the liquid canoverflow over the edge of the cup when the latter is full.
In the operation of theapparatus made in accordance with my invention, a quantity of the ground coffee, which may be finer than the coffee previously found suitable in the brewing of coffee, is placed in the coffee-filter cloth 14, which is then inserted into the removable section ll of the apparatus such a mannerjt'hat the swinging brackets'12have their pinsl3inser'ted into the filter-clothjust inside ofthe ring 15. The hinged pipe 17 is th ushed" into" the body of ground coffee until the circular nozzle 19 is in the middle of the body of coffee and at the bottom thereof. 1 Or, if desired, these steps may be reversed by inserting the nozzle 19 into the filter-cloth 14 after the latter has been supported on the brackets 12 and the very finely ground coffee might be introduced thereafter to the desired depth in the filter-cloth 14. A supply of hot water will also be introduced into the water jacket 1 to the desired level. Thereupon, the valve in the pipe 17 is opened to provide a supply of hot water to the body of coffee in the apparatus. Because of the laterally and upwardly directed openings in the nozzle 19 the ground coffee will not only become loosened during the application of the water fed into the same but the body of coffee will rise upwardly along the sidesof the filter-cloth 14 in the direction of exit of the body of water through the cloth, and some water will, of course, accumulate inthe pocket thus formed above the body of coffee. As the brewing proceeds the liquid cofiee will be received into the pan'8 whereit will drip out very gradually into the urn 4, thus causing an efiective mixing of the brewed coffee to prevent any stratification of the same with consequent undesirable variation in the strength of the coffee drawn off from the faucet o. The brewed coffee can thus be served at once from the urn 4 before the brew is completed, thus avoiding the usual delay which is caused by the necessary mixing of the brewed coffee. l Vhen the required amount of cofiee has been brewed the valve in the pipe 17 will, of course, be closed, and when the brewing has been entirely completed the removable section 11 may be, if de sired, lifted off from the top of the appa ratus and the lid 16 may be placed on top of the urn 4, in the water jacket 1, so that the urn and the Water jacket together with the cover 16, may be transported to another position or place for the withdrawal of the hot brewed coffee from the faucet 5, as desired.
While I have described my invention above in'detail I wish it to be understood that many changes may be made therein without departing from the spirit of the same.
